Hi,

binutils 2.9.1.0.6 is available now. I'd like to release it public
this weekend. Please test it as much as you can.

Thanks.

This is the beta release of binutils 2.9.1.0.6 for Linux, which is based
on binutils 2.9.1 plus Linux/ARM support and some x86 assembler changes.

There was some problem on Linux/alpha. The binaries generated by the new binituls may not run correctly on Linux/alpha. It turned out it was a bug in the alpha dynamic linker in glibc 2.0.6. The current glibc 2.1 and glibc 2.0.7 should be ok.

This release should work on linux/x86/alpha. There are some ELF bug fixes. But I don't know if it fixes all the bugs reported on linux/sparc, Linux/MIPS and linux/PPC. I'd like to hear reports on them. I'd like to release it to public soon. Please test it as much as you can.

Please report any bugs related to binutils 2.9.1.0.6 to hjl@lucon.org.

Changes from binutils 2.9.1.0.5:

1. A MIPS assembler ".align" bug is fixed. 2. bfd.h, bfd.h and bfdlink.h are included in the binary package.

Changes from binutils 2.9.1.0.4:

1. 2 x86 16bit mode assembler bugs, "ret" and "movb $35,0x4(%di)", are fixed.

IMPORTANT: The .plt format that the Alpha was using was not thread safe. So I changed it. The new format is *not* binary compatible with the old, thus you must use glibc 2.0.4 to get an ld.so that can understand it.

Note that the new ld.so knows how to deal with the old .plt format, so old libraries will still work, but they should be relinked eventually for performance reasons.

The file list:

1. binutils-2.9.1.0.6.tar.gz. Source code. 2. binutils-2.9.1.0.5-2.9.1.0.6.diff.gz. Patch against the previous beta source code. 3. binutils-2.9.1.0.6-libc5.x86.tar.gz. Precompiled Linux/x86 binaries for libc 5. 4. binutils-2.9.1.0.6-glibc.x86.tar.gz. Precompiled Linux/x86 binaries for libc 6 (glibc 2.0.5c or above).

The primary ftp sites for the compiler/C library:

1. ftp://tsx-11.mit.edu/pub/linux/packages/GCC 2. ftp://sunsite.unc.edu/pub/Linux/GCC

The beta directory is in private/tofu under the GCC directory. Most of my stuff can also be found at

ftp://ftp.yggdrasil.com/private/hjl ftp://ftp.kernel.org/pub/linux/devel/gcc

To install the binary package, please follow the procedure very closely. Please backup/save all the files you are instructed to delete and you should do gzip -dc binutils-2.9.1.0.6-libc5.x86.tar.gz | tar tvvf - or gzip -dc binutils-2.9.1.0.6-glibc.x86.tar.gz | tar tvvf - to see what is in there. Please do back up before you remove things.

To install for libc 5, PLEASE DO 1. su root 2. cd / 3. rm -f /usr/bin/encaps /usr/bin/nm 4. gzip -dc binutils-2.9.1.0.6-libc5.x86.tar.gz | tar xvvf - 5. ldconfig To install for libc 6 (glibc 2.0.5c or above), PLEASE DO 1. su root 2. cd / 3. rm -f /usr/bin/encaps /usr/bin/nm 4. gzip -dc binutils-2.9.1.0.6-glibc.x86.tar.gz | tar xvvf - 5. ldconfig Now you have the new gas/binutils under /usr/bin and /usr/ix86-linuxaout/bin. You have to use /usr/ix86-linuxaout/bin/as and /usr/ix86-linuxaout/bin/ld -m i386linux if you want to use a.out as and ld directly. I have changed the target names for Linux/x86 and Linux/x86 (a.out) to ix86-linux and ix86-linuxaout respectively. The precompiled binaries are installed under /usr/ix86-linux and /usr/ix86-linuxaout. You should make appropriate symbolic links if you have a different name for the Linux/x86 target, like i586-unknown-linux.

If you have an old linux library in the a.out format and you cannot obtain the newer version in the ELF format for whatever reason, you can try "objcopy --remove-leading-char" on the a.out library and see if it can link with your code in ELF. For Sybase client libraries, I did

# cd sybase/lib # for f in *.a do objcopy --remove-leading-char $f done

It seems to compile/link fine with libc 5.4.2x. But I don't know if it really works or not. The resulting binaries should work if the libc ABI used by the old library is unchanged in the new libc.

According to Bruce Milner <Bruce.Milner@genetics.utah.edu>:

Just a quick note about your example using objcopy for sybase. The sybase a.out libraries "are" dependent on a changed feature of the libc ABI. The ctype macros changed to a byte order independent format (little endian). In order to use the sybase libraries, one needs to rename the the ctype table variables in the sybase library files and link in an old version of the libc's "C-ctype.o ctype-info.o" files.

Thanks.
